To all whom it may concern:

Be it own that we, Haarwnnr. W. Wane, a citizen of the United States of America, and a resident of Cresskill, county of organ, and State of New Jersey, and

Eowann H. Srrcnnns, a citizen of the United a to a mixing device adapted to be employed in conjunction with a carburetor tor preparing a gaseous charge for fuel and similar purposes.

@ur invention consists in-a novel form of supporting structure whereby the device may be employed as an attachment to existing apparatus;

in order that our invention may be fully understood, we will now proceed to describe an embodiment thereof, having reference to the accompanying drawings illustrating the same, and will then point out the novel teatures in claims.

in the drawings: Figure l is a view in side elevation oi a carburetor and pipe connection for connecting the same with an internal combustion engine, showing in dotted outline, a mixer constructed in accordance with my invention, connected thereto. a Fig. 2 is a view in central transverse section through the mixer and portions of the carburetor and pipe connections. Fig. 3 is a detail and face view ot the mixer showin the same detached from the carburetor on pipe connections. .Fig. 4 is a similar end View looking in the opposite direction. Fig. 5 is a" sectional view showing the mixer 1 when applied to a threaded pipe connection in lieu of the flanged connection shown in Figs. 1 and 2.

The mixer comprises, in general, but two elements, one a stationary main supporting element, and the other a rotatably mounte V paddle or fan wheel. The stationary eleent comprises a cylindrical shell havmg an outwardly flaring flange at one end thereof, and provided with spider arms 12 at the other end thereof, and aoentral supporting stud 13 secured to the said spider arms. The ten or paddle wheel element comprises a sleeve l i which finds a bearin upon the stud l3, and obliquely dispose" perforated I blades 15. The edges or the blades are preferably serrated as is shown at 16, the entire set of blades bein conveniently struck up from a perforate blank as will be understood by reference to the drawlugs.

A device oi this character is adapted to be mounted between the flanges l7 and 18 of a carburetor 19 and a pipe connection 20 such as are commonly employed in connection with internal combustion engines. A gasket 21 is commonly employed between the said flanges, and the flanged portion 11 oil the cylindrical shell 10 may conveniently be nipped between the gasket and the said flanges. Where a flanged joint is not used, but in lieu thereof a threaded joint is employed such as is shown at 22 in Pg. 5, a collar 23 may he first screwed into place in the interiorly threaded portion, and the flanged portion 11 ot' the cylindrical shell 10 thereafter nipped toward it and the end of tFhe'eateriorly threaded part as is shown'in ig. 5.

The device when placed in the position shown is located in the path of the incoming gaseous currents comrising carbureted air or other mixture. 'l ese gaseous currents impinging upon the fan or paddle wheel will rotate the same at a high rate of speed, and the blades ofthe fan or paddle wheel will act upon the gaseous fluid to further mix its constituent mixture and increasing the eficiency thereof. The serrated edges of the blades and the perforations therein have considerable value in this connection as they provide a large area of irregular surface which constantly crosses the path of the gaseous mixture.

lhe deviceis usually and preferably em; ployed in a vertical position as is shown in the drawings, the fiow of the gases in the direction of the arrow in Fig.2, tending to slightly lift the tan or paddle wheel, and hence to reduce the rotational friction thereof. in order to prevent any accumulation of condensed moisture or liquid fromother sources from collecting around the shell 10 between it and the plpe connection 2Q, we preferably provide the flanged portion 11 parts, thereby improving the with one or more draining openings 24 which will permit liquid to drain back to the carbureter.

By making the supporting structure in the form shown, it will be noted that we are enabled to use the same in connection with the common form of carbureter in which the throttling valve 25 is disposed very near to the flange 17. As a matter of fact the throttling valve 25 in one position usually extends beyond the face of the flange, but we conveniently construct the shell portion 10 of sufficient length to cause the paddle or fan wheel to clear the same even under such conditions, as will be well understood by reference to Fig. 2 of the drawings.

While we have shown the edges of the blades serrated because this is the preferred form thereof, it may be. noted that this feature is not claimed in the present application. This subject matter is contained and claimed in a separate co-pending application filed August 20, 1910, Serial Number 57 8,200.

What we claim is:

1. As an article of manufacture, a mixer for gaseous fluids arrangedto be disposed in the path of gaseous currents to be acted upon, comprising a tubular casing having an outwardly'fiaring flange at one end thereof, and provided intermediate its ends with a fan or paddle wheel rotatably supported thereby.

2. As an article ,of manufacture, a mixer for gaseous fluids arranged to be disposed in the path of gaseous currents to be'acted upon, comprising a tubular casing having an outwardly flaring flange at one end thereof, spider arms at the opposite end and a central stud supported by the said spider arms, and a rotatable fan or paddle wheel provided with a tubular bearing sleeve rotatably mounted upon the said stud.
